Any chain restaurant applying for an operating license in Florida ought to have to complete a course in the Char-Hut methodology. This little Florida franchise, which opened its first outlet in 1976 to sell char-grilled burgers, onion rings, and hot dogs, is doing so many things right that itÂ?s easy to lose track. It serves nutritious food at low prices Â? a fresh-ground, lean burger thatÂ?s won approval from the American Heart Association; side orders of whole baked sweet or Idaho potatoes, black beans and rice, cole slaw, and plantains; salads topped with grilled tuna steak or chicken. Further, it locates its franchises in western communities and reaches out to its neighbors with specials Â? discounts for local teachers and faculty, free food for youngsters wearing uniforms on game days, Jr. burgers and hot dogs for every A a kid earns on her report card. It has stuff for vegetarians. Discounts for seniors. It's so squeaky-clean, itÂ?s almost painful; the food is delicious. With every patty flipped over a hot grill, Char Hut sews up one small tear in fast foodÂ?s tattered reputation.
